CHARLES M. FYFE. OF BROOKLYN. NEW YORK.

DARNING AND WEAVING DEVICE.

Specification of Letters Patent.

Patented .1 une 2c, 1911.

Application filed June 6, 1916. Serial No. 101,908.

To a whom. it may concern:

Be it known that 1, CHARLES M. Frrn, a citizen of the United States, and a resident of the city oi New York, borough of Brooklyn, in the county of Kings and State of New York. have invented a new and Im proved Darning and -Weaving Device, of which the following is a full, clear, and exact description.

This invention relates to a device for darning or weaving. and it relates more particn larly to a machine which is intended to be operated by hand or as an attachment to a sewing machine.-

The invention has for its general objects to provide a darning device of the character referred to which is of comparatively simple and inexpensive construction and so designed that darning can be easily and quickly accomplished without any special skill on the part of the user.

A more specific object of the invention is the provision of a darning or weaving mael'nne which embodies a reeiprocatory thread-carrying needle movable in a constant path, and in cooperation therewith is a work carrier which is movable step by step when in one position for enabling the warp threads to be laid, and then movable step by step after having turned through ninety degrees more or less to permit the woof threads to be laid, the warp threads being automatically acted on to produce a shed, just as in weaving.

A more specific object of the invention is the provision of a darning device. After the work is applied to the holder, the needle threaded and the parts properly adjusted, the darningoperation will be performed entirely by simply turning a crank or operating an equivalent device.

A- further object is the provision of a work holder and operating means for moving it step by step in two periods between which the work holder is turned through ninety degrees, and during the turning the shed-forming means is automatically" brought into play by being operatively connected with the actuating mechanism.

Another object of the invention is to provide a darning device in the nature of an'at tachmcn't tora. sewing machine, the thread lazing carried by the needle of the sewing' machine and the shuttle of the latter being also employed to cause iliterlocking of the threads so that the atlarhinent embodies merely a work holder and the means for operating it to cause the laying of the warp and woot' threads.

\Vith such objects in view, and others which will appear as the description pro- .ceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with partirnlarity in the following description and claims appended hereto.

In the accompanyin drawings. which illustrate certain cmbmlimcnts ofthc invention andwherein similar characters of retcrence indicate corresponding parts in all the views.

Z'and S. f \Yhen. the .wori:';-carrier moves from the position shown "in Fig. i to that shown in F 1g.- 8 the warp threz'uds'are laid, and as the work carrier moves" to the left from the po sition shown in'Fig. 8 toits initia'l .-position, tlie'woof threads are laid. Thework carrier is moved during the warp and woof laying periods step by step, the inore-ment being controlled with either one offthe racks (3 or? disposed respectively at adjacentsidesof the body?) of the carrier. The star wheel is controlled by an 'escapement 8, 1 that the wheel can 4 turn step by step a nd this in turncontrols the step by step movement of the carrier. The movemeut'is produced by a motor whlch 'is in the form of a winding drum 9 fastened to the top of thebed A, this drum being actuated by a spring 10; and winding:- around the drum is a flexible element 11 which extends under the CfllI'lCl" and connects with a lug-12 dependingfrom the bottom thereof. \V'ithin the chamberlB, under the slot 2, is a fixed post-11} which hasapulley 15 disposed to rotate on' a vertical axis and lying 1n the plane'oi the-fiexible-element or cord 11. This cord'is adapted to )ass around the guide pulley 15 in placing thework holder in its starting position, 'as shown-in Fig. 7.

. I'n movingsthe .Work holder to this positionthe drum 9 unwinds and its spring "is placed under a. strong tension, which tends to draw the Workcarrier back to its final'p'osition. Thepull on the cord 11 is always in one direction, yet-it produces {a movement. Tot the work carrier first to the right from the insition shown in Fig. 7 and when the limitto the right is reached it imparts a quarter turn to the work carrler, as shown in Fig. 8; and I thereafter the latter moves to the. left fromthe position shown in Fig. 8. Vlfhen moving'to the right the starv wheel is in engagement with the rack bar 6 so tha-t'the' moveof the iya star wheel 5 whi'ch meshes 'the work holder is- 3, I I 138L346 merit to-the: right is stop by step. each step being so timed that the needle can pass back i and forth mice through the work. \Vhen the work holder travels to the left the star. wheel .is in engagement with the rack bar .7, which .causes the step by step movement so that intern' ediate each step a back and forth woof 7 threadcan be laid. The work carrier is re- I body, the passage being formed of two quad a x-ant recesses disposed with their vertices.

meeting, as shown in Fig. (i,-so that sutlieient clearance :is provided to permit the work holder to turn through ninety degrees. The work a applied'armind the upper end of the work holder. and clamped by an elastic band lflfor equivalent. means, the opening to be darned being stretched across the-top of the work holder. A fter the work is thus-applied the holder B is moved to the right untilthe position shown in Fig; is reached, when the holder is turned anticlockwise through ninety degrees and then it is movedto. the left. During this placing ot the work holder to starting position, the escapement 8 can beheld out of engagement withtlielescapeinent or star; wheel 5, to per mit the latterto freely rotate;

The.needle. frame (.is of any desired conthread feeds t o thefnee'dle 24. This needle is of that type liav-ingan eye adjacent its point and it 15 otaplength c'lependelnt. on' the ca paeity of the work holders- The needle ishorizontal and-reciproeates. ox'er the top-01' theworkholderso that'the warp and woo-f threads willhbelaid in a horizontal .pl-i-inei.-

I pported err-its si'deli The-1 needle" frame-G. is reciprocate-d by a- 1 mounted ona-fiilcia'un bolt 26;' This lever has a free end 27 workinglthrough asl ot1'2S in the base of the frameC, and the lever is connected by a link 29 with a crank 30 mounted on a vertical shaft 31. This shaft" is connected by a train of gears 32 .with an operating wheel or crank 33 disposed to one side ofthe bed, the gears being housed witbin the chamber 1. The escapementlm er R ,means'" on the d. needle frame, as shown in At theside of the work carrier B opposite from the needle 24 is a shuttle carr er D .pin 39 on the reeiprocatory actuating bar 40, said pin extending upwardly through the slot and connecting with the shuttle carrier I). By this means the shuttle d is passed through the loop of the warp or woof threads with each stroke of the needle, as shown in Figs. 9 to 11 inclusive. The actuating rod is pivotally connected at 41 with the upper end of a post 42, the lower end of which extends downwardly to the bed A, where it connects at 43 with a. lever 44 fulcrumed at 45 in the bed A. This lever has a free end 46 which is adapted ,to'

be engaged by a wiper 47 on-the shaft 31,

woof threads.

so that with each rotation of the shaft the lever 44 is moved in one direction to mov'e the shuttle carrier also in one direction, and

at the same time a spring 48 is placed under tension to cause the lever and shuttle carrier to move in the opposite direction when the arm or wiper 47 passes the level.

In order to lay the woof threads -i-t is necessary to form the warp threads into a shed. For this purpose oscillating hcddles E and F are arranged across the upper or operative portion of the work holder B5 The upper heddle device E is a bar 50 journaled in bearings 51 on a cross bar 52 carried by a bracket 53. This bracket 53 is connected by a pivot fastener 54 to the upper end of a standard 55 which rises from the body of the work -holder so as to move therewith.

The bracket or arm 53 can be swung to one side from the normal osition shown so as to permit thework to eeasily adjusted to the work holder. The shaft or bar 50 has spaced fingers 56 projecting from one side and spaced fingers 57 projecting from the opposite side the fingers 56 alternatin with the fingers-57, and the fingers are a apted to engage thewarp threads alternately. The shaft 50 may be oscillated in any suitable manner, as, for instance, by means of an arm 58 detachably connected at 59 with a rod 60. This rod has its lower end connected with an arm 61 on a rock shaft 62 which in turn has a crank arm 63, the pin 64015 which is adapted to engage in a slot 65 of an actuatin-gframe 66.- As shown in Fig. 2, the slot 65 has an open end or mouth 67 so that the crank pin 64 can. move into the slot when the work carriermakes'a uarter turn after the warp threads have. een

laid and the work is ready to receive the In Figs. 1. to 4 and 8 the work carrier is in. a position for the laying of the woof threads, and consequently the crank pin 64 will be engaged with the actuating frame 66, but during the la ing of is osed ninety degrees from the actuating 66, will be clearly apparent by a comparison of Figs. 7 and 8. The frame 66 its lower end 1s connected b a link 69, Fig.

'1, with a bell-crank lever 0 fulcrumed at 71 in the chamber 1. A bar 72 is connected .withthis lever and is reciprocated in any suitable manner, as, for instance, by a wheel 73 which has a pin 74 arrangedto engage a la 75 on the rod 72 and move the same to the right, Fig. 1, and it also has a pin 76 arranged to en age a lever 77 which in turn engages alug 8 on the rod 72 to move the latter to the left, it being assumed that-the wheel 7 3 turns in a clockwise direction. The wheel 7 3 is mounted on a shaft 79 which is rotated by the train of gears 32 from the hand-wheel 33. The lower heddle device F comprises a rock shaft 50' which has oppositely disposed sets of fingers 56 and 57 engage the remaining warp threads t to lower or raise the same, whereby the shed is formed for the passage 0 the needle in laying the woof threads. A few of the woof threads t are shown as having been laid in Fig. 5. The top surface of the work holder may be formedby alternating sets of bars 80 and 81. which. lie. respectively under the fingers 56 and 57. These bars'reciprocate insynchronism with the oscillation of the heddles so as .to allow clearance for the threads in forming the shed. When all the bars are in mid position or flush. they lie close to the warp threads when they are not in shed formation. As the bars 80 move upwardly the bars 81 move downwardly, this being accomplished by the lever 61, Fig. 5, engaging in recesses ,82 and 83 in the members 4; 85, which carry the bars 80 and 81.

After the work an is adjusted to the holder x13 and the latter is. moved to the position from the-shuttle the manner shown in Figs. 9 to 11 inclusive.

After the op osite side of the opening has been reache the" work holder B turns through ninety degrees and the warp threads are fo sheds The woof threads are inter ocked fixed as to its movement relatively to the needle. When the laying of the woof threads is finished the machine is stopped and the upper heddle device E is discon I ed into a shed so that the. needle can pass t e -woof threadthrou h-the $125 with the shuttle thread T as. the shuttle 1 '10 v of the opening-to bedarned. 1

Referring to Figs. to 18 ;inclusive, the

nected from the so that the bracket 53v with the parts that' it carries can be swungto'one-side for permitting the work tobe removed. -D uring the la mg of the warp threads the needle passes. tween the .upper and lower heddle devices E and F.

'The re employed with the necessary additions to ularf mechanism of the sewing machine IS operate thelwork carrier-and theheddle devices; The darni device is essentially of thesame construction as'the deviee already-\ described, except that the shuttlecarrier is dispensed with, since the shuttlenoarrier H of the se'v'v ing'machine takes its-place, and

place. The shuttle operating shaft 85 of the sewing machine is operatively connected by any suitable means with the heddle actusting frame 66. In the present instance the operating connection comprises a shaft 86 geared to the shaft '85, and on this shaft 86 1s adisk 87 havingp'ins88 andg-89 which engage respectively a lever 90 and a lug 91 on the. longitudinally movable bar 92., -The lever is engageable witha' lug 93;on the bar-92 to inovethe bar in one direction, .while i the pin89 engaging the lug 91 'moves the bar i in the opposite direction. This bar 92 is connect'ed at 94 withthe heddle'actuating frame 6 6.. The sameshaft 85 controls the actuation of the escapement 95 of the star wheel 5. This escapement 95 is opcratedhy any suitable means, such,'for instance,as acam- 91$ onthe shaft' 85 .operating' througl1 the lever 97 or; equivalent means.
